The Ultimate SwiftUI Layout Generator
Building responsive, scalable UI layouts is the foundation of modern front-end engineering. While the CSS Flexbox model has become the absolute industry standard for aligning and distributing space among items in a container on the web, native mobile SDKs implement these exact same concepts using entirely different syntax, paradigms, and naming conventions.
This generator serves as a universal translator for UI developers. It allows you to build your layout visually—manipulating direction, alignment, justification, and spacing—and automatically translates your configuration into exact, production-ready SwiftUI code. Whether you are centering a button, building a complex navigation bar, or laying out a dynamic grid of cards, this tool guarantees mathematically perfect UI alignment.
Layout in SwiftUI
SwiftUI abstracts layout into highly declarative, specialized Stack views: HStack (horizontal/row), VStack (vertical/column), and ZStack (depth/z-index). SwiftUI handles layout distribution very differently from traditional Flexbox models. While the cross-axis alignment is handled elegantly by the alignment parameter on the Stack itself, main-axis distribution (like CSS space-between) is achieved by placing flexible Spacer() views among your children to dynamically consume the remaining empty space on the screen.
Frequently Asked Questions
What is the main axis versus the cross axis?
In flex-based layouts, the main axis is defined by the flex direction (e.g., horizontal for a Row, vertical for a Column). The cross axis runs perpendicular to it. Properties like justify-content affect the main axis, while align-items controls the cross axis.
How do I center an item perfectly?
To center a child both horizontally and vertically, you must align it on both axes. In standard CSS or Tailwind, this means setting both justify-content to center and align-items to center on the parent container.
Does this tool generate responsive code?
This tool generates the base layout structure. For true responsiveness (like changing from a row on desktop to a column on mobile), you will need to add platform-specific media queries or responsive breakpoints (e.g., Tailwind's md:flex-row classes).
